ocarpus Incisa Forst., Xos. !m; mid 597. 



A large tree, common throughout the Territory 

 in low lands. It is reserved by the natives when 

 they blear land for cultivation, and its fruit 

 (Bread-fmit) is a common diet everywhere 

 below 3,000 feet. Above that altitude the bread- 

 fruit does not flourish, and the long red-fruited 

 pandanus takes its place as a native fruit tree. 



Here and there the natives plant bread-fruit 

 seedlings, or sow the nuts in their gardens, but, 



generally speaking, they content themselves with 

 protecting the young trees that shoot up 

 naturally on farm lands. 

 Artocarpus incisa is one of the large and more 



permanent of the first crop of re-growth that 

 springs up on cleared land. Unlike the 



Macaranga, Evodias and other purely light- 

 demanding species, whose life is very short, the 

 bread-fruit will stand some shade, and in turn 



r 



makes a dense cover for the more permanent 



forest species. 



The wood is soft and of no account. 

 Native name. — Sekeri (Suku).
